As the conference is in person, please be advised that proof of full vaccination (list of accepted vaccines below) or negative COVID test within 72 hours of the event is required before picking up your attendee badge.


Given the new CDC guidance on masks, masks will be voluntary.

Valid forms of vaccination proof include a valid photo ID and:

  • Documentation from a healthcare provider; or 

  • Personal digital COVID-19 vaccine record issued by your State, local, or foreign governmental jurisdiction; or 

  • Personal digital COVID-19 vaccine record issued by an approved private company.

If you are not vaccinated because of a medical or religious exemption, you will need to show proof of a negative COVID test within 72 hours of picking up your attendee badge at the conference.
